| Abstract: | In this paper ,a new approach developed for ground-fault localization on ungrounded and high-resistance grounded system is described .A relative-voltage comparison algorithm is used .with digital relay,zero-sequence signal generator and remote ground-fault indicators , the system can deal with intermittent fault,multiple faults on the same phase and inverted ground fault. |
